UTF-8 as default charset for response body decoding

[sanekyy]

JsonApi spec:

https://jsonapi.org/format/#content-negotiation-servers

Servers MUST send all JSON:API data in response documents with the header Content-Type: application/vnd.api+json without any media type parameters.

Dart HTTP client by default decode use latin1 charset.

So it's not decoding correctly UTF-8 json:

dart-lang/http#175

Let's use charset UTF-8 as default.

This is a valid point. Ideally, the decision making and decoding logic should be decoupled in such a way that it can be configured (e.g. set the default encoding) or replaced.
